HC-SR04 Ultrasonic Distance Measuring Sensor Module

HC-SR04 Ultrasonic Sensor Distance Measuring Module (Blue)

The HC-SR04 Ultrasonic Sensor is a high-precision distance measuring module designed for both Arduino and Raspberry Pi projects. It provides accurate non-contact distance detection using ultrasonic sound waves, making it ideal for robotics, automation, and obstacle avoidance applications.

This module features an integrated ultrasonic transmitter, receiver, and control circuit, allowing it to measure distances from 2 cm to 400 cm (1 inch to 13 feet) with an impressive accuracy of ±3 mm. It operates on DC 5V and requires only four pins (VCC, Trig, Echo, GND) for easy interfacing with your microcontroller.

Compact, lightweight, and reliable, the HC-SR04 delivers high sensitivity and a narrow 15° measuring angle, making it perfect for precise distance detection in robotics and embedded systems.
